Formation & geological history

Formed through the regional metamorphism of magnesium-rich limestones (dolomites) or ultrabasic rocks. It is most commonly found in Precambrian to Mesozoic metamorphic belts.

Uses & applications

Used primarily in jewelry (beads, pendants), ornamental carvings, luxury decorative objects, and as a component in traditional 'healing' stones in various cultures.

Geological facts

Yellow jade is highly prized in Chinese culture as it represents imperial power and longevity. It is technically a nephrite mineral, which is tougher and more break-resistant than steel due to its densely interwoven fibrous structure.

Field identification & locations

Identify by its 'soapy' or greasy feel and high toughness. In the field, look for water-worn river boulders with a soft, buffed surface. Common locations include China (Liao Ning Province), Russia, British Columbia, and New Zealand.
